In the Royal Box, the young royals shared some laughs as they adjusted their Wimbledon-issued Panama hats.

For the occasion, Princess Charlotte wore a cobalt blue dress styled with short ruffled sleeves, a gathered waist, and an A-line midi skirt. While the designer remains unknown, the piece is most likely a custom creation.

On her feet, Charlotte wore the same pair of white ballet flats she debuted at this year's Trooping the Colour. The best match so far are the Papouelli 'Missi' style, however, the limited product images available don't provide a clear view of the heel, making a definitive comparison impossible. I'm currently waiting to hear back from the brand for confirmation.

Charlotte completed the look with a new piece of jewellery, debuting the Accessorize 14ct Gold-Plated Ocean Charm Bracelet. Thanks to Amalia for the fabulous find!

Princess Charlotte joined her father, Prince William, brothers Prince George and Prince Louis, and grandparents Carole and Michael Middleton at the base of Mount Snowdon to welcome Catherine after she successfully summited the highest peaks in Scotland, England, and Wales within 24 hours.

For the final Snowdon leg of the challenge, the Princess was accompanied by her brother, James Middleton. The family then gathered for a photo to celebrate the remarkable achievement.

The young princess was visibly moved as she was reunited with her mother at the finish line.

A beautiful moment between mother and daughter as Charlotte and Catherine embrace.

Princess Charlotte was dressed casually, wearing a navy J.Crew Girls' 'Teddy'  sweater paired with her patch-pocket jeans, which she first wore in the portrait released to mark her 11th birthday.

One of my reader's has suggested they may instead be the GAP Kids High Rise '70s Flare Jeans. After closely looking at the pockets, seams, and stitching, I'm confident these are a match for Charlotte's jeans! ​

On her feet were a pair of Adidas 'Gazelle' Kids Sneakers in Focus Blue / Solar Orange / Core Black.

For the occasion, the young princess wore an ivory dress with some suggesting it could be a bespoke piece by Alessandra Rich, however this is unconfirmed.

A closer look at the bodice reveals a double-breasted bib front panel adorned with six self-covered buttons and framed by clean vertical pleats. It is topped by a Peter Pan collar delicately edged in white scalloped lace with a small, centered self-fabric bow. Also visible are delicate tonal embroidery details and a scattering of blue dots, which coordinate with the colour of her mother's dress and her brothers' ties.

A look at the back of the dress.

On Charlotte's feet was a new pair of white leather ballet flats. 

The best match so far are the Papouelli 'Missi' style, but there isn't a side profile stock photo for me to compare the heel, so I can't say with 100% certainty. Thanks to @GabiK_blogoKate for the suggestion.

The princess wore her hair in a half-up style, neatly secured with a white Jane Taylor Mini Organza Bow Hair Clip.

Mirroring her mother’s jewellery, Princess Charlotte wore a triple-strand pearl bracelet, although the way the strands cross over suggests it may actually be a necklace wrapped three times around her wrist.

In the photo, the young princess is wearing patch pocket jeans with a ​women's navy and red striped cable-knit sweater also by Polo Ralph Lauren.

UPDATE: Princess Charlotte wore the jeans again to greet her mother after she completed the Three Peaks Challenge, giving us a much better look at them. They were initially thought to be a pair by Ralph Lauren, but the pocket size and stitching are not a match and the RL pair do not have a back yoke.

Kensington Palace later released a short video from Cornwall, featuring Charlotte, to thank the public for their birthday wishes.

Charlotte is seen wearing a pale blue sweater and t-shirt with her navy ​Mayoral Cotton Jersey Shorts.

The tee is believed to be the 4F Boy's 'Chasing Waves' Print oversize T-shirt in turquoise.

The light blue sweatshirt hoodie appears to be H&M as a few readers have suggested.

The portrait and video were taken on the same day as the photograph released to mark the 15th wedding anniversary of the Prince William and Catherine, Princess of Wales.

The family of five arrived at the chapel alongside King Charles and Queen Camilla, as well as fellow members of the British Royal Family, marking the first time in three years that the Waleses have attended the Easter service.

For the Easter celebrations, Charlotte repeated a look she first wore last Christmas Day, pairing a bespoke Catherine Walker wool coat with coordinating Tory Burch cap-toe ballet flats.

@katemiddletonstyled suggests the Self-Portrait Pleated Chiffon Dress in Blue (US$335) as a possible option.

Her hair was worn half-up, with two delicate side braids meeting at the back, while the rest of her hair fell loose.

The Wales family was joined by extended members of the royal family and led by King Charles III and Queen Camilla during the traditional walk to the church on the Norfolk estate.​

The princess echoed her mother’s look in an all-brown ensemble.

She debuted a bespoke Catherine Walker wool coat from the British couture house long favoured by her mother and her grandmother, the late Princess Diana. 

Beneath the coat, a glimpse of a dark red pleated dress can be seen.

We've had a couple of suggestions for the dress including a Patachou red flannel design (€155.60), and a Self-Portrait Burgundy Chiffon Long Sleeve Dress, though the limited photos prevent a definitive identification.

Complementing the look were a new pair of Tory Burch Cap-Toe Ballet Flats in Dark Cocoa.

Princess Charlotte wore her hair in a half-up style, finished with a velvet bow. ​A reader has suggested the Velvet Bow Hair Clip by Accessorize, and it looks like a perfect match to me!

Pre-recorded in the festive Inner Hall at Windsor Castle, the mother-daughter pair performed Holm Sound by Scottish composer Erland Cooper—a serene piece inspired by nature, connection, and motherhood. 

​The intimate performance showcased not only their musical talent but also the close bond they share, bringing a touching start to the holiday season

Princess Charlotte looked elegantly festive in a navy blue La Coqueta 'Diana' Merino Jumper tucked into a Boden tartan kilt skirt. 

Here's a closer look at her gold bracelet.

She completed the look with a large sparkly gold bow in her hair from Patachou.

Before entering the church, the young royals added their names to the Christmas tree garland.​

​The Waleses were accompanied by members of the extended royal family and the Middleton's for a service celebrating "Love, Compassion and Connection."

For tonight’s celebration, Princess Charlotte wore a lustrous deep-blue velvet dress, coordinating perfectly with her brothers, who were dressed in smart navy suits. 

She wore a new pair of navy patent leather flats paired with coordinating tights. They appear to be the Panache Girls Ballerina Bow Pumps.

Her hair bow appears to be from Milinnery. Thanks to reader Grace for the ID!

Before the match, the British royals met with Spain’s Princesses Leonor and Sofía — an encounter that offered the young royals a chance to connect while also serving as a symbolic gesture of sportsmanship ahead of the fiercely contested final.

Princess Charlotte’s enthusiasm for the game shone through as she passionately cheered on the Lionesses, who triumphed over Spain after a 1–1 draw in extra time, clinching victory with a 3–1 win in the penalty shootout.

For the occasion, Princess Charlotte re-wore her navy Guess chiffon polka dot dress, previously seen at last year’s Wimbledon Men’s Singles Final​.

She was also spotted wearing a white button-up by NEXT. 

Charlotte completed the look with her trusty Papouelli “Siena” Mary Jane flats.

Princess Charlotte wore a custom-made sleeveless ivory textured dress with contrast piping and ruffle detailing at the bodice, created by her mother’s go-to designer, Sarah Burton. The dress features a tiered skirt and attached belt that ties in the back.

She paired it with cream-colored Papouelli “Siena” Mary Jane flats, a style she’s worn before.

The sun-smart Princess sported a pair of $86 Ray-Ban RB9070S Kids Sunglasses in Polished Havana.

Her accessories included a silver Pandora snake chain slider charm bracelet (US$80) with three charms: a green stone for her May birth month, a silver disk charm, and a rose gold Nala charm from Disney’s The Lion King reflecting a family favourite. She also sported a bubblegum pink manicure, her first public nail polish appearance.
